I think the extras were both a source of benefit and vice for this anthology. It's always fun to look into the author's personal thoughts regarding stories...but a few of the character career futures, and all of the relationship futures shoulda probably been left alone. The fact it seemed pretty implied none of the relationships actually lasted and a lot of the character traits went under some drastic changes...well it made the whole thing seem pretty fake.
Of course maybe it's just a translation problem and in reality all 4 relationships sustained throughout the series in which case I can not only forgive the resounding character changes, but I can also relish in the successful future of all of them.
